Short description of error
[Please fill out a short description of the error here]
In Node Editor there is a problem with connection lines: they are not shown or disappear when reconnecting other nodes
Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
This problem appears when Blender uses non-default user startup file, as I have investigated so far.
Cause even after Load defaults then Save config and reopen Blender ( it starts with my startup file ) does not solve this problem.
I think that is something not right if user have to rebuild his workplace from scratch every time when software is updated.
Please investigate this case. Thank you.
